When I first joined FireSprite, I was placed on a graduate team that was creating a tool and app to create and interface with digital comic books, art books, soundtracks and preview content respectively, on the PlayStation 4. The tool to create the content was a Windows application developed in C#, the app that displayed the content on the PlayStation was written in C++. This tool is still in use internally. Over time we expanded the tool to the point that it became Turing-complete and it could be used to make games.
Formerly known as CAVE (Creative Audio Visual Experience), Project Campfire consists of 2 applications. One of which is an editor that runs on a Windows machine. It is used to create the bonus content applications. The other runs the bonus content application - much like the PHP code for this site that interprets the data for each project (while there are seemingly multiple pages, there are only actually 2 if you look at the URL). This runs on the end user's machine, PS4, XBOX, PC, etc.
